Arduino and python-firmata

I just spent five hours trying to figure out why  none of the Firmata libraries for Python were working over my serial connection. I was wondering why the previous program remained on the board and none of the signals sent were hot.

Hint: you need to load Firmata first onto the board before it can understand the protocol. Oh. Duh.

Only “OldStandardFirmata” (Firmata 2.0) seems to work with my version of python-firmata. The newer Firmata PDEs can talk Firmata 2.1 and 2.2, but I’m too tired to figure them out.
